Storage management and caching in PAST, a large-scale, persistent peer-to-peer storage utility

by Antony Rowstron, Peter Druschel , 2001
"... This paper presents and evaluates the storage management and caching in PAST, a large-scale peer-to-peer persistent storage utility. PAST is based on a self-organizing, Internetbased overlay network of storage nodes that cooperatively route file queries, store multiple replicas of files, and cache a ..."

Nosql databases for rdf: An empirical evaluation

by Iliya Enchev, Sever Fundatureanu, Paul Groth, Albert Haque, Andreas Harth, Daniel Miranker, Juan Sequeda, Marcin Wylot - In International Semantic Web Conference (2 , 2013
"... Abstract. Processing large volumes of RDF data requires sophisticated tools. In recent years, much effort was spent on optimizing native RDF stores and on repurposing relational query engines for large-scale RDF processing. Concurrently, a number of new data management systems— regrouped under the N ..."

, to the best of our knowledge, the first systematic attempt at characterizing and comparing NoSQL stores for RDF processing. In the following, we describe four different NoSQL stores and compare their key characteristics when running standard RDF benchmarks on a popular cloud infrastructure using both single

Which NoSQL Database? A Performance Overview

by Veronika Abramova, Jorge Bernardino, Pedro Furtado, Which Nosql Database, A Performance Evaluation, Veronika Abramova A, Jorge Bernardino A, Pedro Furtado B
"... NoSQL data stores are widely used to store and retrieve possibly large amounts of data, typically in a key-value format. There are many NoSQL types with different performances, and thus it is important to compare them in terms of performance and verify how the performance is related to the database ..."

Abstract Evaluating NOSQL Technologies for Historical Financial Data

by Ansar Rafique, Ansar Rafique
"... Today, when businesses and organizations are generating huge volumes of data; the applications like Web 2.0 or social networking requires processing of petabytes of data. Stock Exchange Systems are among the ones that process large amount of quotes and trades on a daily basis. The limited database s ..."
Abstract - Add to MetaCart
” brings an effective solution through the provision of an efficient information storage capability. NOSQL is an umbrella term for various new data store. The NOSQL databases have gained popularity due to different factors that include their open source nature, existence of non-relational data store,

Analysis and Classification of NoSQL Databases and Evaluation of their Ability to Replace an Object-relational Persistence Layer

by Kai Orend , 2010
"... This work deals with distributed databases from the NoSQL movement, which gained popularity since April 2009. It explains some of the basic problems of distributed databases and the technologies that are used to solve them. Furthermore, a selection of NoSQL databases is analyzed and classified. In ..."

. In order to evaluate their ability to replace an object-relational persistence layer, their feature sets were compared to the requirements of an already existing web collaboration and knowledge management software. This application was then enhanced with a support layer for a NoSQL database and later

Bridging SQL and NoSQL

by John Roijackers, Dr. G. H. L. Fletcher, Dr. A. Serebrenik , 2012
"... A recent trend towards the use of non-relational NoSQL databases raises the question where to store application data when part of it is perfectly relational. Dividing data over separate SQL and NoSQL databases implies manual work to manage multiple data sources. We bridge this gap between SQL and No ..."

Data Integration over NoSQL Stores Using Access Path Based Mappings

by Olivier Curé, Robin Hecht, Chan Le Duc, Myriam Lamolle
"... Abstract. Due to the large amount of data generated by user interactionsontheWeb,somecompaniesarecurrentlyinnovatinginthedomain of data management by designing their own systems. Many of them are referred to as NoSQL databases, standing for ’Not only SQL’. With their wide adoption will emerge new ne ..."

The End of an Architectural Era (It's Time for a Complete Rewrite

by Samuel Madden, Daniel J. Abadi, Stavros Harizopoulos - Proceedings of the 31st international , 2005
"... In previous papers [SC05, SBC+07], some of us predicted the end of “one size fits all ” as a commercial relational DBMS paradigm. These papers presented reasons and experimental evidence that showed that the major RDBMS vendors can be outperformed by 1-2 orders of magnitude by specialized engines in ..."

is required. In this paper we show that current RDBMSs can be beaten by nearly two orders of magnitude in the OLTP market as well. The experimental evidence comes from comparing a new OLTP prototype, H-Store, which we have built at M.I.T. to a popular RDBMS on the standard transactional benchmark, TPC-C. We

NoSQL: The Death of the Star

Thus, some alternatives to relational DBMSs (e.g. BigTable and C-Store) are blooming. On the other hand, cloud computing is already a reality that helps to sav ..."
